1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

The application and drug development of plant-derived natural products are often limited by their low abundance in medicinal plants and the lack of structural complexity and diversity. Herein, we design a concise enzyme cascade to efficiently produce natural and unnatural protoberberine alkaloids from cost-effective, readily available substrates. Through enzyme discovery and engineering, along with systematic optimization of the berberine bridge enzyme to address remaining manufacturing challenges in protoberberine alkaloid biosynthesis, the high production of drug Rotundine is achieved at an impressive gram-scale titer, demonstrating its industrial potential. More importantly, this cascade also enables the efficient biosynthesis of various unnatural halogenated protoberberine alkaloids. Thus, this work not only unlocks the potential of enzyme cascades in overcoming longstanding challenges in the efficient biosynthesis of plant-derived alkaloids, but also opens avenues to introduce structural complexity and diversity into alkaloids through synthetic biology, offering significant potential for drug development.
